A small amount of preload on the accelerator pump lever, adjusted for slack then remove the slack plus 1/4 turn, makes the accelerator pump function as it is designed.

So many guys run this .010-.015 at idle, which is completely wrong.

Any amount of slack gives a flat spot on initial throttle application off idle.

Any adjustment to the accelerator pump linkage will not have fuel discharging from the booster venturis, period.

If you have fuel discharging from the pump nozzle, then you need to check the pump cavity vent orifice for blockage.
